Subject: [PATCH v1 net 0/2] ECN offload handling for AccECN series

From: Chia-Yu Chang <chia-yu.chang@...ia-bell-labs.com>

Hello,

Please find the v1 ECN offload handling for AccECN patch series for net.
It aims to avoid potential CWR flag corruption due to RFC3168 ECN offload,
because this flag is part of ACE signal used for Accurate ECN (RFC9768).

This corresponds to discussions in virtio mailing list:
https://lore.kernel.org/all/20250814120118.81787-1-chia-yu.chang@nokia-bell-labs.com/
And it was suggested to clarify SKB_GSO_TCP_ECN and SKB_GSO_TCP_ACCECN.

A prior submission is made to net-next:
https://lore.kernel.org/all/SJ0PR12MB68066115C5329872316E6B37DC98A@SJ0PR12MB6806.namprd12.prod.outlook.com/
And it was suggetsed to submit the first two patches to net.

Best regards,
Chia-Yu
